Any further info available?

You could check the memory allocated to each VU process.....

Hi Jamie,

Thanks

Please suggest what parameter needs to be set and what should be its value.

We are still facing the issue

Hi Shahid,

You can set it on a per script/profile basis in a Scenario or you can set it as scenario default in Tools -> Options -> Java Client Preferences -> Maximum JVM Heap Size (MB):. Try setting it to Other and 1024. This is just a suggestion, as we don't know what is happening fully in your instance.

1/ What is your ATS version?
2/ What is the technology you are testing? Web, Siebel, EBS, Forms, something else?
3/ Have you checked log files? Cl:\OracleATS\logs by default

Hi Jemie,

To answer your queries

1. We are in 9.3 version of OAT

2. We are testing EBS (Fin & HRMS & Supply Chain module) which are having mix of forms and html pages.

3. We checked the log file, but could not get much help. Any specific things needs to be checked.

I don't know if it is exactly the same problem you have but it exists a memory leak identified in this release.
Could you please check the logs and tell us if you can see messages like "out of memory" or similar?

Of course, if possible, upgrade to latest release (12.1.0.2 at that time) could be a solution.

Looks like your (application) server cannot handle the load generated by ATS...

"Timeout occurred while waiting for server response"

What do you think?
All the users are failing or only a few?

I just wanted to mention that in some case in 9.3 you could face a memory leak testing EBS/Forms application. This is not necessary your case. Please check log files accordingly.
I also wanted to get more details on the problem:
does it occur after a certain amount of time
does it occur when reaching a specific number of users connected?
does it occur for all users (for one load testing agent) or for some/specific users?

Hi JB,

To answer the question,

1. No it doesn't happen after certain amount of time

2. Yes it occur when a specific number of users.

3. Since we are running with one users (one laptop) and we are setting the virtual users as 100+, we are getting this error.

Regards
Shahid
